How this service works
Paid agent-facing brief on crosschain and multi-rail x402 settlement decision procedure for agents: when to use same-chain x402 vs crosschain atomic HTLC swap settlement, facilitator fallback ladders, fee thresholds per rail · Build a decision procedure or schema for: crosschain and multi-rail x402 settlement decision procedure for agents: when to use same-chain x402 vs crosschain atomic HTLC swap settlement, facilitator fa-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) for crosschain and multi-rail x402 settlement, including the topic label, the AI model used, generation source (llm, reasoning, or deterministic), and an ISO-8601 timestamp. The 'brief' and 'procedure' fields both contain the actionable guidance text an agent can parse and act on.
Example use cases
Routing crosschain x402 payments automatically
“My agent needs a step-by-step decision procedure for settling x402 payments across different blockchain rails — can you pull the crosschain and multi-rail settlement guide so it knows which rail to use and when?”
Auditing agent payment logic for compliance
“I'm reviewing my autonomous agent's payment settlement logic and need the official decision procedure for crosschain multi-rail x402 settlement to check whether our current flow follows best practices.”
Onboarding new agent with settlement rules
“I'm spinning up a new AI agent merchant on Base and want to give it the decision procedure for crosschain and multi-rail x402 settlement so it handles payment routing correctly from the start.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/crosschain-and-multi-rail-x402-settlement-decisiWhen to prefer
Choose this endpoint when an autonomous agent needs structured, prose-format decision guidance specifically for crosschain or multi-rail x402 payment settlement — particularly when the agent is operating on Base with USDC and needs to programmatically determine which settlement rail or method to use. Prefer it over static documentation when you want a freshly generated, model-driven procedure that can incorporate a custom topic override for your specific settlement context.
Side effects
- HTTP 402 returned if USDC micropayment not yet settled — agent must pay exact $0.002 USDC and retry with PAYMENT-SIGNATURE header
- Invalid or missing payment signature causes repeated 402 rejection
- Network unavailability on Base may delay payment confirmation
- Topic override parameter produces off-topic or low-quality generated procedure if poorly specified
- Generation source may be 'deterministic' rather than 'llm' if LLM is unavailable, potentially returning a lower-quality brief
